In order to take full advantage of the potential of high-speed FDM 3D printers, Polymaker designed the PolySonic line of filaments that includes PolySonic PLA and PolySonic PLA PRO. The PolySonic filaments offer ultrafast extrusion rates, supreme precision and great layer adhesion. On top of that, the PolySonic PLA PRO filament has increased toughness, durability, impact strength similar to ABS, and flexural strength significantly higher than ASA or PETG. From among the PolySonic filaments, this material answers the needs for rugged functional parts.
Polymaker spools are compatible with advanced multi-material systems, ensuring seamless and hassle-free integration with printers using these systems.
The PolySonic PLA PRO filament fulfills the three key criteria for a high-speed filament. These criteria are flowability, formability, and functionality:
Even though PolySonic PLA PRO was designed for very fast printing speeds, it is also possible to use standard PLA printing speeds of 50-100 mm/s as opposed to the 100-300 mm/s maximum printing speed for this filament. For the standard printing speeds the extrusion temperature range is 190-210 ºC and at printing speeds of 100-300 mm/s the PolySonic PLA PRO can be extruded at 210-230 ºC. This wide range of available printing temperatures and speeds makes the PolySonic PLA PRO filament a very versatile material that will give great results in both standard 3D printing contexts as well as high-speed printing applications.
Polymaker's PolySonic PLA PRO is an ideal material for the ultrafast additive manufacturing of functional prototypes or end-use products that need an excellent surface finish and consistent mechanical properties regardless of the printing speed. For general prototyping, modeling or decorative applications, see the high-speed PolySonic PLA filament by Polymaker.
The packaging in which Polymaker presents its filaments is highly studied and carefully designed to preserve the quality and condition of its filaments. In this case, PolySonic PLA PRO is presented inside a vacuum-sealed bag together with a desiccant sachet to prevent the filament from getting wet. This bag is self-sealing, so once the filament has been used, it can be put back into the bag. In addition, all of this is enclosed in a high quality printed box, to avoid knocks and breakages during shipping.
All products come with printing profiles optimized for BambuStudio, the dedicated software by Bambu Lab. Considering that many BambuLab users are new to 3D printing, preconfigured settings are provided to ensure high-quality results from the very first print, without requiring previous experience. This allows both beginners and experienced users to take full advantage of Polymaker filaments with total confidence.

The ideal printing temperature for the PolySonic PLA PRO lies between 190 and 210 ºC with standard settings and 210-230 ºC with high speed settings. It is recommended to use a printer with a heated bed (30-60 ºC), and set the layer fan to 100 %. The recommended printing speed is 50-100 mm/s for standard mode and 100-300 mm/s for high speed mode. The retraction distance for a 0.4 mm nozzle is 0.5-3 mm, and the best retraction speed is 30-60 mm/s. A heated chamber is not required.
PolySonic PLA PRO should be properly stored to avoid the filament from getting humid. An ideal solution is to store it in a vacuum sealed packaging (with the Slice Engineering filament drying capsule for even better results), an intelligent filament container or in the PolyBox storage box that keeps the filament dry during printing. If the filament absorbs too much moisture, it should be dried at 55 ºC for 6 hours.
The recommended support materials for PolySonic PLA PRO are PolySupport or PolyDissolve S1 by Polymaker. Should any adhesion issues occurs, the Magigoo adhesives can be used.
